Move all executors to the internal folder package. This PR also comes
with additional breaking changes.
Changes:
- refactor: move all executors to the internal/executor package.
- refactor: update naming patterns for constants, variables, custom
types, etc.
- fix(breaking): renamed the update command to edit.
- fix(breaking): update the flags for the switch command to make it
more generic.
- fix(breaking): renamed the show-account-relationship flag to
show-relationship.
- fix: update the print message from the whoami command.
Allow users to specify their preferred configuration directory by using
the top level flag (a.k.a 'global flag') --config-dir. This also
introduces the design of baking top level flags into the executor.
Add Enbas code. So far Enbas can:
- Allow the user to register the application and log into GTS on their
behalf. The scope is limited to read for now.
- Show instance details.
- Show local and remote accounts.
